<div>Hi Max,</div>
</div>
</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;"><br>
</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;">The 0.9 SimpleITK release is compiled against the libpng1.5, so if you are using the binary from binstar you will have to use the old matplotlib.</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;"><br>
</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;">If using the latest matplotlib is not critical for you, then the following recipe for creating a virtual environment (sitkpy) should work:</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;"><br>
</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;">conda create -n sitkpy anaconda libpng=1.5</div>
<div>
<p style="margin: 0px;">conda install -c https://conda.binstar.org/simpleitk/channel/main SimpleITK</p>
</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;">conda install libpng=1.5</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;"><br>
</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;">This (1) creates the virtual environment with our choice of libpng version, all other anaconda packages (i.e. matplotlib) will be compatible with this version; (2) install SimpleITK which will
unfortunately upgrade you to libpng 1.6 (our bad) and then (3) downgrade to libpng 1.5 so that everything really works.</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;"><br>
</div>
<div style="font-size: 14px; font-family: Calibri, sans-serif;">If you are willing to compile SimpleITK on your machine you (will always be compatible with the libpng, matplotlib,... versions you have):</div>

<div>Hi All,</div>
<div><br>
</div>
<div>I am using SimpleITK with Anaconda for Python 2.7.10. After installing SimpleITK from binstar, I was only able to import SimpleITK after downgrading libpng to version 1.5.13. However, this downgrade is causing problems with other packages using libpng
in some way (e.g. matplotlib).</div>
<div>Is there a way to use the newer libpng library instead with SimpleITK or would that cause problems for ITK itself?</div>
<div><br>
</div>
<div>Thanks</div>
